Hi All,

   Two for the (free) price of one! :)

   For those who aren't regular earthquake watchers, the following website
   gives a quick overview of the seismic activity from a network of seismographs
   around the world.  Its fairly basic information, but gives a 24 hour
   view.

   Just at the moment (and for the next couple of hours) it is showing, on
   the same seismogram, both large quakes in Japan.

   Notes:

     o.  Clicking on each trace will give you a larger version.

     o.  The scans update every 30 mins

     o.  the date-time group is MDT (Mountain Time) in the US ... 
         which corresponds to Colorado ... the location of a World 
         Data Center (WDC) for this data.
